The app has a control range with the ability to control between zero and five lights and doors, depending on the use case. By means of a red-green indicator, the user is shown the connection status of the server. In the settings area of the app the server connection details can be entered. Depending on the use case, the controls for the lights or doors can be switched on and off. For the individual lights and doors, the corresponding theme as well as the message can be set. In addition, further settings for the transmission can be selected.

Verdict
The clearest difference is update cadence: API at every 6 days against MQTT's every 11 months. API also leads on iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
